Potato Insecticide Evaluation

The Colorado potato beetle (CPB) and the potato leafhopper (PLH) are two important insect pests that need to be managed for profitable potato production. The CPB, in particular, is troublesome because it has developed resistance to insecticides in the carbamate, organophosphate, and pyrethroid chemical groups. Currently, insecticides in the neonicotinoid group provide effective control of CPB, but there are concerns that with continued use of neonicotinoids this resilient pest also will develop resistance to this group of insecticides. The objective of this study was to evaluate a new insecticide called cyantraniliprole, trade marked CyazypyrTM by Dupont, for its effectiveness against our common insect pests and its usefulness in a CPB insecticide resistance management program
